摘要
本文采用微分电位溶出法测定２１３例脑梗塞患者血清中Ｃｕ、Ｐｂ、Ｃｄ、Ｚｎ、Ｆｅ、Ｍｎ等微量元素的含量，并与６９例正常人对照。结果表明，各患者组血清中Ｆｅ、Ｍｎ与正常组无明显差别，Ｐｂ、Ｃｄ含量均显著高于正常组（Ｐ＜０．０１）；急性脑梗塞患者（５天内）组Ｃｕ／Ｚｎ比值明显高于对照组（Ｐ＜０．０１），但随时间延长Ｃｕ／Ｚｎ比值逐渐降低；恢复期（３１～６０天）及脑梗塞后遗症两组患者血清Ｃｕ低于对照组（Ｐ＜０．０５），Ｃｕ／Ｚｎ比值远低于对照组（Ｐ＜０．０１），用Ｆｅｉｓｈｅｒ判别分析法比较Ｐｂ、Ｃｄ含量及Ｃｕ／Ｚｎ比值对疾病的作用，证明了Ｐｂ的贡献率为１９．５％，Ｃｄ的贡献率为４１．３％，Ｃｕ／Ｚｎ比值的贡献率为３９．２％，诊断符合率为９６．２５％。
The concentration of the trace elements Cu,Pb,Cd,Zn,Fe,Mn in blood serum using differential potentiometric stripping to detect was presented.The nomal samples were 69,the patients with atherosclerosis cerebral infarction samples distinct differ from the nomal samples.the Pb,Cd in blood serum of paitent were higher than that of the nomal samples(P<0.01).The rate of Cu/Zn of patient with the acute cerebral infarction within 5 days is higher than that of the contrast samples(P<0.01) but reducing as the time is long.The Cu in sequelae of cerabral infarction is lower than that of the contrast samples(P<0.005).The ratio of Cu/Zn is far lower than that of the contrast samples analysised using Ferisher analytical the contribution rate of Pb is 19.5%,the contribution rate of Cu is 41.5%,the contribution rate of the tatio of Cu/Zn is 39.2%, The rate which according with diagnose is 96.5%.
